Is the Vitaran procedure generally effective?

I am considering the Vitaran procedure. I am curious if it is actually effective and if the results are noticeable, rather than looking like I haven't had anything done. I want to know which areas Vitaran helps with—such as skin regeneration, hydration, elasticity improvement, fine line reduction, or skin texture refinement—and specifically, if it is suitable for dry and sensitive skin. I also want to know if I can feel the effects after just one session, or if I need to receive multiple sessions consistently to see better results. I have been disappointed before with procedures where I spent money but the results were barely noticeable, so I really want to see some explosive results. I am extremely curious to hear reviews from those who have tried Vitaran.
